Try rebooting your iPad. Simultaneously press and hold the home and power buttons until the Apple logo appears onscreen, then release both buttons. Let us know if this helps.Sorry everyone. New to this site. I upgraded my IPad 2 to IOS7. Now all my apps (the ones that needed to be upgraded) are grayed out and/or state waiting. I can't open or delete them for reinstalling. Any suggestions. I tried to reset using the sleep menu key...no luck. Can't power down. Frustrated and feeling a little stupid. Any help appreciated.
